FASTENING DEVICE.

Specification of Letters Patent.

Patented May 19, 1914.

Application filed October 24, 1913. Serial No. 797,072.

1 Be it known that I, THOMAS C. WYANT, a citizen of the United States, residing at Dixon, in the county of Dixon and State of Nebraska, have invented certain new and useful Improvements in Fastening Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fastenin devices for "securing crossed timbers toget er; and

it consists of a bolt having a head atone end and having tongues at its other end portion as hereinafter fully described and claimed.

In the drawings, Figure l is a side view of portions of two crossed timbers provided with a fastening device according to this invent-ion. Fig. 2 is an end view of the same. Fig. 3 is a side view of a bolt before being applied to the timbers. Fig. 4 is a front View, and Fig. 5 is a plan View, of the same. The crossed timbers 2 and 3 are such as are used in building construction, or in making farm-gates, wagons and other woodwork. A hole 4 is bored through the timbers where crossed, and a bolt 5 is secured in the hole so ,as to fasten the timbers together. This bolt 5 has at one end a T-shaped head 6, the end portions 7 of which are tapered both in width and thickness and arecurved downwardly toward the other end of the bolt. This head has a flat portion 16 which extends across one timber, and its end portions 7 are then hammered over the edges of the timber so t-hat'they clamp its sides tightly between them. The lower portion of the bolt is split longitudinally and in line with the head. thereby forming two parallel tongues 8: These tongues are thrust through the hole 4, and their protruding end portions are bent in opposite directions, crosswise of the head and under the timber, and the extreme end portions of the tongues are bent upwardly against the sides of the timber and are forced into engagement with the first said timber. In this manner the two timbers are rigidly secured together, at a very small expense, without being notched or otherwise Weakcued, as the bolts cost very little when forged in large quantities, and the cost of cutting screwthreads and supplying nuts is obviated.

What I claim is:

A fastening bolt for crossed timbers, comprising a shank provided at one end with a head having a flat portion adapted to extend across the top of one timber and having tapering end portions adapted to be hammered over the edges of the said timber, the other end-portion of the said shank being split longitudinally to form two tongues which are separable crosswise of the head and which are adapted to be hammered over the bottom and sides of the other timber.

In testimony whereof I have aflixed my signature in the presence of two witnesses.

THOMAS C. WYANT.
